Control information sending and receiving method and apparatus

A terminal apparatus, comprising:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
• determine L pieces of control information from M pieces of control information based on a priority rule, wherein a total quantity of bits of the M pieces of control information is greater than a channel capacity of the terminal apparatus, wherein the M pieces of control information comprise M1 pieces of uplink control information and M2 pieces of sidelink control information, and wherein types of the M1 pieces of uplink control information comprise at least one of a hybrid automatic repeat request, a scheduling request, and channel state information, and wherein types of the M2 pieces of sidelink control information comprise at least one of a sidelink hybrid automatic repeat request, a sidelink scheduling request, and sidelink channel state information, and wherein M is a positive integer greater than or equal to 2, M1 is an integer greater than or equal to 0, M2 is a positive integer greater than or equal to 1, and L is an integer greater than or equal to 0 and less than or equal to M;
• and
• send the L pieces of control information;
• wherein determining the L pieces of control information from the M pieces of control information based on the priority rule comprises:
• determining the L pieces of control information from the M pieces of control information based on the priority rule and the channel capacity, wherein a total quantity of bits of the L pieces of control information is less than or equal to the channel capacity.

A non-transitory, computer-readable medium, wherein the computer-readable medium stores program code, and when the program code is run on a computer, the computer is enabled to:

• determine L pieces of control information from M pieces of control information based on a priority rule, wherein a total quantity of bits of the M pieces of control information is greater than a channel capacity of the computer, wherein the M pieces of control information comprise M1 pieces of uplink control information and M2 pieces of sidelink control information, and wherein types of the M1 pieces of uplink control information comprise at least one of a hybrid automatic repeat request, a scheduling request, and channel state information, and wherein types of the M2 pieces of sidelink control information comprise at least one of a sidelink hybrid automatic repeat request, a sidelink scheduling request, and sidelink channel state information, and wherein M is a positive integer greater than or equal to 2, M1 is an integer greater than or equal to 0, M2 is a positive integer greater than or equal to 1, and L is an integer greater than or equal to 0 and less than or equal to M;
• and
• send the L pieces of control information;
• wherein determining the L pieces of control information from the M pieces of control information based on the priority rule comprises:
• determining the L pieces of control information from the M pieces of control information based on the priority rule and the channel capacity, wherein a total quantity of bits of the L pieces of control information is less than or equal to the channel capacity.
